Pump Units of the Type HДМ (NDM) are intended for operation under high temperatures / pressures in mining and metallurgy. These Pumps are using normally for handling of oil and / or oil-products, incl. easily-inflammable and / or generally-dangerous solutions, of max.: Density 1 850 kg/m3 ; volume concentration of up to 0.2 mm-sized solid inclusions below 0.2%; cinematic viscosity from 30 x 10-6 m2 / s, under temperatures from -50 °С up tо +450 °С.

These Pump Units are designed in the full accordance with requirements of API 610 Type BB5: Delivery Range up to 700 m3 / h; Pump Head up to 2 200 m. In accordance with either certain operational conditions or Customers’ requirements, these Electric Pump Units are available with a variety of Electric Motors, controls and measuring instruments, while chambers of their end-face seals could be provided with cooling- or heating jackets.
